  • Can't read CDs, can't create USB... how do I install Ubuntu?

    - by user68080
    Hello everyone and thank you in advance for your time. I have troubles with the latest Ubuntu distribution: since I upgraded to 12.04 Ubuntu has started having troubles (internal errors, packages that crash repeatedly, I can't install new packages, Ubuntu Software Center crashes, Java apps that worked stopped working and display weird mistakes, files were corrupted... a mess). I ultimately decided to format everything and install 12.04 from scratch. I made a backup and everything, but now I have troubles installing ubuntu 12.04. Specifically, a CD I burned with Brasero that works on another PC is not read by my laptop (not at boot phase, nor inside Ubuntu), and when I try to create a USB with Ubuntu (following the instructions I found on the ubuntu site) Startup Disk Creator stops at 22% saying that "the codes do not match". Any idea on what to do next? No, I can't buy a new PC.

  • Deleted files not increasing available free space on Ubuntu (as reported by df -h)

    - by Homunculus Reticulli
    I am writing data munging scripts (python and bash), to munge data and import large quantities of text files into a database. I am currently in the test phase, so I am generating several K's of files and deleting them (the files consume about 20G of space). After a test run, I delete the files (sometimes without having imported into the database). I notice that there is a steady decrease in the amount of free space on my disk (as reported by df -h). I don't understand this, as I use rm * (in the data directory), and in the cases where I use Nautilus, I empty the Trash bin as well. Similarly, I notice that when I import the data into the (postgresql) database, and then delete the data from the tables using DELETE FROM tablename;, the size consumed in the postgresql data directory does not go down either. Currently, I have lost approximately 200G from hard drive, and I need to reclaim that - but don't know what to do to reclaim it - any ideas?. I am running Ubuntu 10.0.4 LTS + postgresql 8.4

  • Next step after first few years at work [closed]

    - by juniordeveloper87
    Its been 2 years since graduating from uni and working in a IT solutions company as a programmer. My initial year was particularly exciting when we were trying to get a fresh product up to speed. The product has now gone live and are in the maintenance phase. My current day job involves merely bug fixing and also small designing/implementing change requests and also helping resolve issues faced from clients. Slowly I feel a little 'normal' in my role. I wonder how I can make myself stand out. (I work in a company of no more than 200 people) Or what should be the next step I take after 2 years doing programming? Thanks!

  • When should I decide what language and platforms I will use for a project?

    - by Mikalichov
    During your development process, when is the recommended phase to decide what platform to aim for, and what language to use? I figured that it would be better to choose at the beginning what would be your target platform, as it would affect your design decisions, and limit the language you are supposed to use. However, I have heard several stories of people developing their game with whatever language they were the most confident with, and then porting it to the various platforms. So, what is the best moment to choose? Before, during, after? If there is not one best choice, what factors should affect the decision?

  • Poll: How long will you wait before using Solaris 11 on production systems?

    - by nospam(at)example.com (Joerg Moellenkamp)
    When Sun released Solaris 10, it was my first migration phase to a new Solaris major release while being part of Sun. At that time i heard a lot of comments between "Oh, we will install it on new systems on day 1" to "oh ... not that fast ... we will wait ... we are not that fast ... we will do it in a year". I would like to get some additional insight and so i set up the poll plugin for s9y to get the answer to the question "How long will you wait before using Solaris 11 on production system?". Thank you for your participation!

  • Ubuntu One slow download sync speed

    - by Ian M
    I am having problems syncing my Ubuntu One files with my Ubuntu 12.04 fresh installation. Everything went well during the setup phase. Now, I am trying to sync back in my folders in my U1 account and the transfer speed is extremely slow. I am averaging a 15kb/s transfer speed. I tried uninstalling ubuntuone-client and reinstalling it. It did not fixed the problem. Right now U1 is stuck downloading a 50mb file. It is taking forever. Any ideas?

  • Les Variables de plus en plus proches du CSS, WebKit commence à les supporter de manière expérimentale

    Les Variables de plus en plus proches du CSS WebKit commence à les supporter de manière expérimentale L'équipe de WebKit, le moteur de rendu utilisé entre autres par Chrome et Safari, va supporter de manière expérimentale une des avancées les plus attendues (et fondamentales ?) du CSS : les variables. Jusqu'ici, seules des alternatives (comme less.js) permettaient d'utiliser ces variables dans des feuilles de style. Problème, ces « tours de passe-passe » demandent une phase de compilation. La solution du W3C, qui sera donc très prochainement supportée par le build Canary de Chrome et plus largement par les Nightly Builds de Webkit, est beaucoup plus simple.

  • How to get several frequency ranges at the same time in fmod?

    - by Rootosaurus
    After reading documentation and tutorials about fmod I still have a question about frequency ranges. I've found how to get a frequency range using low and high pass DSP at the same time on the main channel, but I can't find how to get several ranges at the same time. For example I want, for a specific phase of my game, to hear range 400 to 600Hz and 1000 to 2000hz of the same sound. I tried to create a channel by range, but it doesn't seem to work (or maybe I do something wrong). How can I do that ? Thank you

  • Including an embedded framework using a cross-project-reference: Header no such file or directory

    - by d11wtq
    I'm trying to create a Cocoa framework by using a cross-project reference in Xcode. I have 2 projects: one for the framework; one for the application that will use the framework. This framework is not intended to be stored within the system; it is an embedded framework that lives within the application bundle. I have successfully made the cross-project reference, marked the framework as being a dependency of my target, added a Copy Files build phase that puts the framework in Contents/Frameworks/ and added the framework to the linker phase (I checked the little "Target" checkbox; I've also done it manually by dragging the framework into the linker phase). My framework's install directory is correctly set to @executable_path/../Frameworks. However, when I try to build my app it: a) Correctly builds the framework first b) Correctly copies the framework c) Errors because it cannot find the master header file in my framework I have verified that the header is there. I can see it in the app product that is partially built. ls build/Debug/CioccolataTest.webapp/Contents/Frameworks/Cioccolata.framework/Headers/Cioccolata.h build/Debug/CioccolataTest.webapp/Contents/Frameworks/Cioccolata.framework/Headers/Cioccolata.h I have been able to successfully build the app by copying my framework into /Library/Frameworks (I can then delete it again after the successful build), but this is a workaround, I'm looking to find it out why Xcode doesn't find the framework's master header file without it being copied to a system directory. Is copying it to the app bundle during the build not sufficient?

  • Soapui & populating database before

    - by mada
    SoapUi & database data needed Hi, In a J2ee project( spring ws + hibernate +postgresql+maven 2 + tomcat),We have created webservices with full crud operations. We are currently testing them with SoapUi (not yet integrated in the integration-test maven phase ). We need tomcat to test them. Actually before the phase test, with a maven plugin, only one time, some datas are injected in the database before the launch of all tests through many sql files. But the fact is that to test some webservices i need some data entry & their Id (primary key) A- What is the best way to create them ? 1- populate one of the previous .sql test file. But now we have a big dependency where i have to be careful to use the same id use in a insert in the sql file in SoapUi too. And if any developper drop the value, the test will broke. 2- create amongst the .sql file test a soapui.sql where ALL data needed for the Sopaui test will be concentrated. The advantage is that the maintenance will be much more easy. 3-because i have Ws available for all crud operations, i can create before any testsuite a previous testsuite called setup-testsuiteX. In this one, i will use those Ws to inject datas in the databse & save id in variables thanks to the feature "property transfer" 4-launch the soapui test xml file with a junit java test & in the Setup Method (we are using spring test), we will populate the database with DbUnit. Drawback: they are already data in the database & some conflicts may appear due to constraint.And now i have a dependency between: - dbUnit Xml file (with the value primary key) - sopaui test where THOSe value of primarykey will be used advantage: A automatic rollback is possible for DbUnit Data but i dont know how it will react because those data have been used with the Ws. 5- your suggestion ? better idea ? Testing those Ws create datas in the DB. How is the best way to remove them at the end ? (in how daostest we were using a automatic rollback with spring test to let the database clean) Thanks in advance for your hep & sorry for my english, it is not my mother thongue. Regards.

  • How do I configure the hbm2java maven2 plugin to generate POJOs for all mapping files

    - by naor
    Hi. I am trying to migrate my ant build to maven2. in my build.xml I invoke the hbm2java in the following way: <hibernatetool destdir="/src/generated/"> <configuration configurationfile="${env.ITP_HOME}/core/xml/hibernate/hibernate.cfg.xml"> <fileset dir="/xml/hibernate"> <include name="*.hbm.xml"/> </fileset> </configuration> <hbm2java/> </hibernatetool> my hibernate.cfg.xml is: <hibernate-configuration> <session-factory> <property name="hibernate.dialect">org.hibernate.dialect.Oracle10gDialect</property> <property name="hibernate.connection.driver_class">oracle.jdbc.driver.OracleDriver</property> </session-factory> in my maven2 POM file I have: <plugin> <groupId>org.codehaus.mojo</groupId> <artifactId>hibernate3-maven-plugin</artifactId> <version>2.2</version> <executions> <execution> <id>hbm2java</id> <phase>generate-sources</phase> <goals> <goal>hbm2java</goal> </goals> <configuration> <components> <component> <name>hbm2java</name> <implementation>configuration</implementation> <outputDirectory>/src/main/java</outputDirectory> </component> </components> <componentProperties> <jdk5>true</jdk5> <configurationfile>/src/main/resources/hibernate.cfg.xml</configurationfile> </componentProperties> </configuration> </execution> but when executing mvn hibernate3:hbm2java i see no files get generated unless they are all listed in hibernate.cfg.xml. Is there a way to specify a fileset in the maven configuration similar to the ant task? thanks, naor

    As a soon-to-be computer science graduate, I have to come realization that I have a long way to go when it comes to the overall design of an application. After spending many semesters of programming from the hip I have come to appreciate the mulling over the needs of an application before diving head first into the coding portion. My question is to the intermediate and expert programmers, how can I improve in the area of the design phase of development?

    I am in evaluation phase of report tool. I prefer RDLC for the same. But I need some examples/samples available in the wild which can guide us on using the RDLC off the shelf. I would be looking for examples from as simple as list of data and as complex as using matrix, calculation, grouping, etc. This will help us to make a reference point if anytime we get stuck up somewhere.

The exception that was thrown is: java.io.NotSerializableException: org.apache.commons.httpclient.HttpClient at java.io.ObjectOutputStream.writeObject0(ObjectOutputStream.java:1156) at java.io.ObjectOutputStream.defaultWriteFields(ObjectOutputStream.java:1509) at java.io.ObjectOutputStream.writeSerialData(ObjectOutputStream.java:1474) at java.io.ObjectOutputStream.writeOrdinaryObject(ObjectOutputStream.java:1392) at java.io.ObjectOutputStream.writeObject0(ObjectOutputStream.java:1150) at java.io.ObjectOutputStream.defaultWriteFields(ObjectOutputStream.java:1509) at java.io.ObjectOutputStream.writeSerialData(ObjectOutputStream.java:1474) at java.io.ObjectOutputStream.writeOrdinaryObject(ObjectOutputStream.java:1392) at java.io.ObjectOutputStream.writeObject0(ObjectOutputStream.java:1150) at java.io.ObjectOutputStream.defaultWriteFields(ObjectOutputStream.java:1509) at java.io.ObjectOutputStream.writeSerialData(ObjectOutputStream.java:1474) at java.io.ObjectOutputStream.writeOrdinaryObject(ObjectOutputStream.java:1392) at java.io.ObjectOutputStream.writeObject0(ObjectOutputStream.java:1150) at java.io.ObjectOutputStream.writeObject(ObjectOutputStream.java:326) at java.util.HashMap.writeObject(HashMap.java:1001) at sun.reflect.GeneratedMethodAccessor80.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at java.io.ObjectStreamClass.invokeWriteObject(ObjectStreamClass.java:945) at java.io.ObjectOutputStream.writeSerialData(ObjectOutputStream.java:1461) at java.io.ObjectOutputStream.writeOrdinaryObject(ObjectOutputStream.java:1392) at java.io.ObjectOutputStream.writeObject0(ObjectOutputStream.java:1150) at java.io.ObjectOutputStream.defaultWriteFields(ObjectOutputStream.java:1509) at java.io.ObjectOutputStream.writeSerialData(ObjectOutputStream.java:1474) at java.io.ObjectOutputStream.writeOrdinaryObject(ObjectOutputStream.java:1392) at java.io.ObjectOutputStream.writeObject0(ObjectOutputStream.java:1150) at java.io.ObjectOutputStream.writeArray(ObjectOutputStream.java:1338) at java.io.ObjectOutputStream.writeObject0(ObjectOutputStream.java:1146) at java.io.ObjectOutputStream.writeObject(ObjectOutputStream.java:326) at java.util.HashMap.writeObject(HashMap.java:1001) at sun.reflect.GeneratedMethodAccessor80.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at java.io.ObjectStreamClass.invokeWriteObject(ObjectStreamClass.java:945) at java.io.ObjectOutputStream.writeSerialData(ObjectOutputStream.java:1461) at java.io.ObjectOutputStream.writeOrdinaryObject(ObjectOutputStream.java:1392) at java.io.ObjectOutputStream.writeObject0(ObjectOutputStream.java:1150) at java.io.ObjectOutputStream.writeObject(ObjectOutputStream.java:326) at com.sun.faces.renderkit.ClientSideStateHelper.doWriteState(ClientSideStateHelper.java:293) at com.sun.faces.renderkit.ClientSideStateHelper.writeState(ClientSideStateHelper.java:167) at com.sun.faces.renderkit.ResponseStateManagerImpl.writeState(ResponseStateManagerImpl.java:123) at com.sun.faces.application.StateManagerImpl.writeState(StateManagerImpl.java:155) at com.sun.faces.application.view.WriteBehindStateWriter.flushToWriter(WriteBehindStateWriter.java:221) at com.sun.faces.application.view.FaceletViewHandlingStrategy.renderView(FaceletViewHandlingStrategy.java:397) at com.sun.faces.application.view.MultiViewHandler.renderView(MultiViewHandler.java:126) at com.sun.faces.lifecycle.RenderResponsePhase.execute(RenderResponsePhase.java:127) at com.sun.faces.lifecycle.Phase.doPhase(Phase.java:101) at com.sun.faces.lifecycle.LifecycleImpl.render(LifecycleImpl.java:139) at javax.faces.webapp.FacesServlet.service(FacesServlet.java:313) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:290) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:206) at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:233) at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:191) at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:127) at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:102) at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:109) at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:298) at org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:852) at org.apache.coyote.http11.Http11Protocol$Http11ConnectionHandler.process(Http11Protocol.java:588) at org.apache.tomcat.util.net.JIoEndpoint$Worker.run(JIoEndpoint.java:489) at java.lang.Thread.run(Thread.java:637) Maybe this is a problem of my design, because I am new in developing Java webapps.

  • KISS: Simple C# application which communicates with a RESTful web service.

    - by Workshop Alex
    Following the KISS principle, I suddenly realised the following: In .NET, you can use the Entity Model Framework to wrap around a database. This model can be exposed as a web service through WCF. This web service would have a very standardized definition. A client application could be created which could consume any such RESTful web service. I don't want to re-invent the wheel and it wouldn't surprise me if someone has already done this, so my question is simple: Has anyone already created a simple (desktop, not web) client application that can consume a RESTful service that's based on the Entity Framework and which will allow the user to read and write data directly to this service? Otherwise, I'll just have to "invent" this myself. :-)Problem is, the database layer and RESTful service is already finished. The RESTful service will only stay in the project during it's development phase, since we can use the database-layer assembly directly from the web applications that are build around it. When the web application is deployed, the RESTful services are just kept out of the deployment. But the database has a lot of data to manage over nearly 50 tables. When developing against a local database, we can have straight access to the database so I wouldn't need this tool for this. When it's deployed, the web application would be the only way to access the data so I could not use this tool. But we're also having a test phase where the database is stored on another system outside the local domain and this database is not available for developers. Only administrators have direct access to this database, making tests a bit more complex. However, through the RESTful service, I can still access the data directly. Thus, when some test goes wrong, I can repair the data through this connection or just create a copy of the data for tests on my local system. There's plenty of other functionality and it's even possible to just open the URL to a table service straight in Excel or XMLSpy to see the contents. But when I want to write something back, I have to write special code to do just that. A generic tool that would allow me to access the data and modify it would be easier. Since it's a generic setup around the ADO.NET Data services, this should be reasonable easy too. Thus, I can do it but hoped someone else has already done something similar. But it appears that there's no such tool made yet...

  • setup.py adding options (aka setup.py --enable-feature )

    - by pygabriel
    I'm looking for a way to include some feature in a python (extension) module in installation phase. In a practical manner: I have a python library that has 2 implementations of the same function, one internal (slow) and one that depends from an external library (fast, in C). I want that this library is optional and can be activated at compile/install time using a flag like: python setup.py install # (it doesn't include the fast library) python setup.py --enable-fast install I have to use Distutils, however all solution are well accepted!

  • How to add dynamically a component in JSF2 during an Ajax request.

    - by Guillaume
    Hello, I am currently trying to dynamically add a new component to the JSF component tree during an ajax request. In fact I add a child to the UIViewRoot component in my AjaxBehaviorListener which is fired on server side during the ajax request process. The issue is that the new component is not rendered. It seems that this component is not taken into account in the render response phase. Could you help me on this issue ? Regards, Guillaume

  • Maven building for GoogleAppEngine, forced to include JDO libraries?

    - by James.Elsey
    Hi, I'm trying to build my application for GoogleAppEngine using maven. I've added the following to my pom which should "enhance" my classes after building, as suggested on the DataNucleus documentation <plugin> <groupId>org.datanucleus</groupId> <artifactId>maven-datanucleus-plugin</artifactId> <version>1.1.4</version> <configuration> <log4jConfiguration>${basedir}/log4j.properties</log4jConfiguration> <verbose>true</verbose> </configuration> <executions> <execution> <phase>process-classes</phase> <goals> <goal>enhance</goal> </goals> </execution> </executions> </plugin> According to the documentation on GoogleAppEngine, you have the choice to use JDO or JPA, I've chosen to use JPA since I have used it in the past. When I try to build my project (before I upload to GAE) using mvn clean package I get the following output [ERROR] BUILD ERROR [INFO] ------------------------------------------------------------------------ [INFO] Failed to resolve artifact. Missing: ---------- 1) javax.jdo:jdo2-api:jar:2.3-ec Try downloading the file manually from the project website. Then, install it using the command: mvn install:install-file -DgroupId=javax.jdo -DartifactId=jdo2-api -Dversion=2.3-ec -Dpackaging=jar -Dfile=/path/to/file Alternatively, if you host your own repository you can deploy the file there: mvn deploy:deploy-file -DgroupId=javax.jdo -DartifactId=jdo2-api -Dversion=2.3-ec -Dpackaging=jar -Dfile=/path/to/file -Durl=[url] -DrepositoryId=[id] Path to dependency: 1) org.datanucleus:maven-datanucleus-plugin:maven-plugin:1.1.4 2) javax.jdo:jdo2-api:jar:2.3-ec ---------- 1 required artifact is missing. for artifact: org.datanucleus:maven-datanucleus-plugin:maven-plugin:1.1.4 from the specified remote repositories: __jpp_repo__ (file:///usr/share/maven2/repository), DN_M2_Repo (http://www.datanucleus.org/downloads/maven2/), central (http://repo1.maven.org/maven2) [INFO] ------------------------------------------------------------------------ [INFO] For more information, run Maven with the -e switch [INFO] ------------------------------------------------------------------------ [INFO] Total time: 3 seconds [INFO] Finished at: Sat Apr 03 16:02:39 BST 2010 [INFO] Final Memory: 31M/258M [INFO] ------------------------------------------------------------------------ Any ideas why I should get such an error? I've searched through my entire source code and I'm not referencing JDO anywhere, so unless the app engine libraries require it, I'm not sure why I get this message.

  • How to get hibernate3-maven-plugin hbm2ddl to find JDBC driver?

    - by HDave
    I have a Java project I am building with Maven. I am now trying to get the hibernate3-maven-plugin to run the hbm2ddl tool to generate a schema.sql file I can use to create the database schema from my annotated domain classes. This is a JPA application that uses Hibernate as the provider. In my persistence.xml file I call out the mysql driver: <property name="hibernate.dialect" value="org.hibernate.dialect.MySQLDialect"/> <property name="hibernate.connection.driver_class" value="com.mysql.jdbc.Driver"/> When I run Maven, I see it processing all my classes, but when it goes to output the schema, I get the following error: ERROR org.hibernate.connection.DriverManagerConnectionProvider - JDBC Driver class not found: com.mysql.jdbc.Driver java.lang.ClassNotFoundException: com.mysql.jdbc.Driver I have the MySQL driver as a dependency of this module. However it seems like the hbm2ddl tool cannot find it. I would have guessed that the Maven plugin would have known to search the local Maven file repository for this driver. What gives? The relevant part of my pom.xml is this: <plugin> <groupId>org.codehaus.mojo</groupId> <artifactId>hibernate3-maven-plugin</artifactId> <executions> <execution> <phase>process-classes</phase> <goals> <goal>hbm2ddl</goal> </goals> </execution> </executions> <configuration> <components> <component> <name>hbm2ddl</name> <implementation>jpaconfiguration</implementation> </component> </components> <componentProperties> <persistenceunit>my-unit</persistenceunit> </componentProperties> </configuration> </plugin>
